[0002] The potato processing industry, such as starch production and potato chip processing, generates a large amount of residue. This residue is rich in dietary fiber and has significant economic value.

[0003] In the process of extracting dietary fiber, there is a lack of targeted disruption methods, and the cell wall structure is not fully destroyed, which affects the extraction rate of dietary fiber. In addition, when performing dietary fiber extraction, it is impossible to control the mixing reaction between the residue and enzymes. Furthermore, the filter residue and filtrate produced after centrifugation are not easy to collect. Therefore, a device for extracting dietary fiber from potato residue is proposed.

[0027] In the description of the embodiments of this utility model, it should be noted that the terms "inner", "outer", "upper", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the utility model product is usually placed when in use.

Therefore, they should not be construed as limitations on this utility model.

[0028] like Figures 1-7As shown, this utility model provides a technical solution: a device for extracting dietary fiber from potato residue, including an extraction box 1. The extraction box 1 provides the installation environment for each process of extracting dietary fiber from potato residue, concentrating the extraction of dietary fiber from potato residue in the extraction box 1. Support columns are set at the four corners of the bottom of the extraction box 1, and the support columns ensure that the bottom of the extraction box 1 is a certain distance from the ground to ensure the installation of the drain pipe 402 and the discharge pipe 405. The crushing component 2 is set in the upper part of the inner side of the extraction box 1 for crushing the potato residue and increasing the contact area between the material and the enzyme. The stirring component 3 is set in the middle of the inner side of the extraction box 1 for stirring the potato residue to make the enzyme and the material evenly mixed. The centrifugation component 4 is set in the lower part of the inner wall of the extraction box 1 for solid-liquid separation of the material after the enzymatic reaction.

[0029] like Figure 1-7 As shown in the embodiment of this application, the crushing component 2 includes a feeding hopper 206, which is located at the top of the feeding pipe 305. Several moving blade groups 204 are arranged above the feeding hopper 206. A fixed shaft 203 is arranged inside the moving blade group 204. A large gear 202 is arranged on the outer wall of one end of the fixed shaft 203. Fixed blade groups 205 are arranged on both sides of the inner wall of the extraction box 1. The feeding hopper 201 is arranged above the fixed blade groups 205. The fixed blade groups 205 cooperate with the moving blade groups 204. Specifically, one of the fixed shafts 203 is connected to the output end of the motor. The motors in this application are all connected to an external power supply and controlled by a control system. The motor drives the fixed shaft 203 to rotate. The moving blade group 204 and the large gear 202 are fixedly arranged on the outer wall of the fixed shaft 203. Therefore, when the fixed shaft 203 rotates, it can synchronously drive the moving blade group 204 and the large gear 202 to rotate synchronously. The large gears 202 mesh with each other. Therefore, in its When the fixed shaft 203 rotates, it can synchronously drive the fixed shaft 203 on the inner wall of the other large gear 202 to rotate synchronously under the meshing action of the large gear 202, and ensure that the two sets of moving blade groups 204 rotate in opposite directions, so as to crush the potato residue entering the extraction box 1. The moving blade group 204 and the fixed blade group 205 are staggered. With their cooperation, the potato residue can be fully crushed. It should be noted that before crushing, the potato residue should be washed to remove the mud, sand, residual starch and other impurities attached to the surface, and the washed potato residue should be drained to reduce the burden of subsequent processing. After processing, the potato residue enters the crushing chamber where the moving blade group 204 is located through the feeding hopper 201. The moving blade group 204 and the fixed blade group 205 work together to crush the potato residue, so as to increase the contact area between the material and the enzyme and create conditions for the subsequent enzymatic hydrolysis reaction.

[0030] like Figure 1-7As shown in the embodiment of this application, the stirring assembly 3 includes a feeding pipe 306, which is located inside the top of the fixed barrel 401. A control valve 307 is provided between the feeding pipes 306. A stirring tank 308 is provided at the top of the feeding pipe 306. A stirring shaft 302 is provided inside the stirring tank 308, and an electric heating wire 303 is provided on its outer wall. Several stirring blades 304 are provided on the outer wall of the stirring shaft 302. A feeding pipe 305 is provided at the top of the stirring tank 308, and a guide tube 301 is provided on one side of it. Specifically, the crushed material enters the feeding pipe 305 under the action of the feeding hopper 206. Since the upper end of the feeding pipe 305 is fixedly connected to the feeding hopper 206, and its lower end is fixedly connected to the stirring tank 308, the material will flow along the feeding pipe. Material 305 enters the mixing tank 308. A discharge pipe 306 is located at the bottom of the mixing tank 308, and a control valve 307 is installed at the discharge pipe 306. All control valves 307 in this application are connected to an external power supply and controlled by a control system. During mixing operations, the control valve 307 at the discharge pipe 306 is in a closed state to prevent material from falling down the discharge pipe 306 to the next process step. After the material enters the mixing tank 308, the operator adds an appropriate amount of water to the mixing tank 308 using a conduit 301. The stirring shaft 302 is connected to the output end of a motor. After the water is added, the motor drives the stirring shaft 302 to rotate. Stirring blades 304 are fixedly installed on the outer wall of the stirring shaft 302. This allows for the mixing and stirring of materials and water to form a uniform slurry. Under the action of sodium hydroxide solution, the pH value of the slurry is adjusted to 4.5-5.5, which is the optimal activity range for commonly used enzymes such as cellulase and pectinase. After the slurry is prepared, cellulase and pectinase are injected into the mixing tank 308 again through the conduit 301. After adding the enzyme solution, the stirring shaft 302 drives the stirring blades 304 to stir again, ensuring uniform mixing of the enzymes and materials. Subsequently, the mixing tank 308 is heated using an electric heating wire wrapped around its outer wall. A temperature sensor is installed at the end of the mixing tank 308 facing the conduit 301, and the temperature sensor is electrically connected to the control system. Since the temperature sensor is existing technology... The process will not be elaborated further here. Temperature sensors are used to monitor the temperature of the mixing tank 308, and the control system maintains the temperature of the mixing tank 308 at 45-55℃. The enzymatic hydrolysis reaction is carried out at this temperature for 2-4 hours. During the reaction, the control system controls the stirring shaft 302 to stir the slurry at regular intervals to ensure that the enzymatic hydrolysis reaction proceeds effectively and evenly. This allows cellulase and pectinase to fully act on the cell walls of the potato residue, decomposing cellulose, pectin, and other substances, and releasing dietary fiber. After the enzymatic hydrolysis reaction is completed, the temperature of the mixing tank 308 is raised to 90-95℃ using an electric heating wire and maintained for 10-15 minutes to denature and inactivate the enzyme proteins, terminating the enzymatic hydrolysis reaction and preventing over-reaction that could damage the structure of the dietary fiber.

[0031] like Figure 1-7 As shown, the centrifugal assembly 4 includes a centrifugal screen 404 located inside the extraction chamber 1. Circular plates 409 are provided at both the upper and lower ends of the centrifugal screen 404. A discharge pipe 405 is provided inside the lower circular plate 409, and a fixed gear 406 is provided on the outer wall of the discharge pipe 405. The fixed gear 406 is meshed with a moving gear 407, and a rotating shaft 408 is provided inside the moving gear 407. Specifically, after the enzymatic hydrolysis reaction is completed, the stirring assembly 3 is stopped, and the control valve 307 is opened using the control system. The slurry will then fall along the discharge pipe 306 into the centrifugal cylinder formed by the circular plate 409 and the centrifugal screen 404. After the slurry enters the centrifugal cylinder, it is rotated, which centrifuges the slurry in the centrifugal cylinder and separates it into filter residue and filtrate. The centrifugal screen 404 is fixedly arranged between the circular plates 409. The upper circular plate 409 and the lower circular plate 409 are connected to the centrifugal screen 404. The material pipes 306 are rotatably connected. The lower circular plate 409 is equipped with a fixed gear 406, which is fixedly installed at the bottom of the circular plate 409 and rotatably connected to the discharge pipe 405. The fixed gear 406 is meshed with the moving gear 407, and a rotating shaft 408 is fixedly installed on the inner wall of the moving gear 407. The rotating shaft 408 is rotatably connected to the fixed bucket 401 and is connected to the output end of the motor. When the motor is started, it drives the rotating shaft 408 to rotate. During the rotation of the rotating shaft 408, it will drive the moving gear 407 to rotate. At the same time, the rotating gear 407 will drive the fixed gear 406 to rotate, thereby driving the circular plate 409 to rotate. This centrifuges the slurry in the centrifuge cylinder formed by the circular plate 409 and the centrifugal screen 404, thereby achieving solid-liquid separation and separating the slurry into filter residue and filtrate.

[0032] like Figure 1-7As shown in the embodiment of this application, a control valve 307 is provided between the discharge pipes 405, and a fixed bucket 401 is provided on its outer wall. A drain pipe 402 is provided at the bottom of the fixed bucket 401, and a control valve 307 is also provided between the drain pipes 402. A scraper 403 is provided between the fixed bucket 401 and the centrifuge screen 404. Specifically, the drain pipe 402 is used to discharge the filtrate generated by centrifugation, while the discharge pipe 405 is used to discharge the filter residue generated by centrifugation. Both the drain pipe 402 and the discharge pipe 405 are provided with control valves 307 to control the discharge of filtrate and filter residue. To facilitate collection and extraction of dietary fiber, a scraper 403 is fixedly installed on the outer wall of the centrifuge cylinder formed by the circular plate 409 and the centrifuge mesh 404. Therefore, when the centrifuge cylinder rotates, it can scrape the inner wall of the fixed barrel 401 to prevent the filtrate from adhering to the inner wall of the fixed barrel. It should be noted that the upper circular plate 409 is rotatably connected to the feed pipe 306, while the discharge pipe 405 is fixedly connected to the lower circular plate 409. The discharge pipe 402 is fixedly connected to the fixed barrel 401. Furthermore, the inner wall of the lower circular plate 409 is funnel-shaped, which facilitates the discharge and collection of filter residue.

[0033] The working principle of this utility model is as follows:

[0034] When extracting dietary fiber from potato residue, the potato residue is first washed to remove impurities such as starch and sugar adhering to its surface. The washed potato residue is then poured into the feeding hopper 201, where it enters the crushing chamber containing the moving blade assembly 204. The motor is started, driving the fixed shaft 203 to rotate. During the rotation of the fixed shaft 203, the large gear 202 rotates. The large gears 202 mesh with each other, thus driving the two moving blade assemblies 204 to rotate synchronously in opposite directions. With the combined action of the moving blade assembly 204 and the fixed blade assembly 205, the potato residue can be crushed. The crushing process increases the surface area in contact with enzymes, promoting the release of dietary fiber. The crushed material is fed into the feed pipe 305 through the feed hopper 206 and falls into the mixing tank 308. At this time, the control valve 307 on the feed pipe 306 is closed. After the material enters the mixing tank 308, the operator injects water into the mixing tank 308 through the conduit 301 and starts the motor to drive the stirring shaft 302 to rotate. During the rotation of the stirring shaft 302, the stirring blades 304 drive the stirring blades 304 to mix the material and water in the mixing tank 308 to prepare a uniform slurry. Then, sodium hydroxide solution is injected through the conduit 301 to adjust the pH value of the slurry to 4.5-5.5. After the pH of the slurry is adjusted, cellulase and pectinase are injected into the mixing tank 308 again through the conduit 301. After adding the enzyme solution, the stirring shaft 302 drives the stirring blades 304 to stir again, so that the enzyme and the material are evenly mixed. Then, the mixing tank 308 is heated using an electric heating wire, and the temperature inside the mixing tank 308 is controlled at 45-55℃. At this temperature, the slurry in the mixing tank 308 is stirred and enzymatically hydrolyzed for 2-4 hours. During the reaction, the stirring shaft 302 is used to stir the slurry at regular intervals using the control system to ensure that the enzymatic hydrolysis reaction proceeds effectively and evenly, so that the cellulase and pectinase can fully act on the cell walls of the potato residue, decompose cellulose, pectin and other substances, and release dietary fiber. After the enzymatic hydrolysis reaction is completed, the temperature of the mixing tank 308 is raised to 90-95℃ using an electric heating wire. Maintain the reaction for 10-15 minutes to denature and inactivate the enzyme protein, terminating the enzymatic hydrolysis reaction and preventing over-reaction that could damage the dietary fiber structure. After the enzymatic hydrolysis reaction is complete, open the control valve 307, and the slurry will fall through the feed pipe 306 into the centrifuge drum formed by the circular plate 409 and the centrifugal screen 404. Start the motor, which will drive the rotating shaft 408 to rotate. During the rotation of the rotating shaft 408, the moving gear 407 will rotate. Since the moving gear 407 is meshed with the fixed gear 406, the fixed gear 406 can rotate synchronously. When the fixed gear 406 rotates, it will drive the circular plate 409 to rotate, thereby centrifuging the slurry in the centrifuge drum to achieve solid-liquid separation. The filter residue and filtrate generated by the centrifugal motion of the slurry are discharged from the discharge pipe 405 and the liquid discharge pipe 402, respectively, and collected.

[0035] In summary, this utility model discloses a device for extracting dietary fiber from potato residue, including an extraction box 1, a crushing component 2, which is located on the upper inner side of the extraction box 1 for crushing the potato residue and increasing the contact area between the material and the enzyme, a stirring component 3, which is located on the middle inner side of the extraction box 1 for stirring the potato residue to ensure uniform mixing of the enzyme and the material, and a centrifugation component 4, which is located on the lower inner wall of the extraction box 1 for solid-liquid separation of the material after enzymatic hydrolysis. This invention, through the meshing of the fixed gear 406 and the moving gear 407, drives the centrifuge cylinder formed by the circular plate 409 and the centrifugal mesh 404 to rotate. During the rotation of the centrifuge cylinder, the slurry after the enzymatic hydrolysis reaction is completed is centrifuged, thereby producing filter residue and filtrate. With the fixed cylinder and the centrifugal mesh 404 separating them, the filtrate and filter residue produced by centrifugation can be collected by the drain pipe 402 and the discharge pipe 405, thereby extracting dietary fiber from the potato residue. With the cooperation of the moving blade group 204 and the fixed blade group 205, the potato residue can be crushed to increase the contact area between the potato residue and the enzyme and promote the enzymatic hydrolysis reaction. With the cooperation of the stirring shaft 302 and the stirring blade 304, the crushed material and the enzyme can be fully mixed. Under the action of the heating wire 303, the temperature in the stirring tank 308 is adjusted to ensure the smooth progress of the enzymatic hydrolysis reaction. After the reaction is completed, the enzyme is inactivated to prevent over-reaction and damage to the dietary fiber structure.
